M M w the stitch receiving lip 7.

Fig. 5 is a detail in elevation of the end of the stitch receiving" lip.

In the illustrated embodiment of the invention the all leather doublelipped insole is made in sections comprising a body portion 1, and anattached strip 2. The sole shaped blank from which the body portion 1 ismade is out from a sheet of leather much thinner and therefore moreflexible than the ordinary insole stock. The strip to be attached. iscut so as to provide an approximately Wedge-shaped cross-section (seeFig. 2) from leather Waste not ordinarily available for use in themanufacture of Welt shoes. The ends of a suliicient length of the stripavailable for use on a sole are skived as at 3 (Fig. 5) and the 'stripintermediate its ends is slit as at l (Fig. 1) to permit the strip to bereadily bent about the periphery of the sole shaped blank. The strip isapplied to the periphery of the blank along its shank and torepart Withthe thick edge of the strip preterably flush with the edge of the soleblank and the sections are joined in this position by any suitablesecuring means, preferably cement (Fig. The edge of the sole as thusformed is then split by a cut 5 extending into the attached strip 2(Fig. 3) sub stantially throughout the length of the strip. A pair ofslits 6, (Fig. 1) are cut' at opposed points in the edge of the insolesubstantially at the breast line. The slit l in the strip 2 forming themarginal portion of the sole emerges from the strip through the skivingat each of its ends, at points opposite the cuts 6 (see Fig. 5). Themarginal portion of the assembled sections extending lor- Wardly of thecuts is turned up and set into the position shown in Fig. t to form Thestitch receiving lip is thus compounded from an inner lip 8 formed fromthe body portion 1 andan outer lip 9 formed from the attached strip 2.In addition to the upturned portion forming the outer lip 9, theattached strip is provided with a portion extending outside of the outerlip 9 which forms the feather 10 of the insole, and a portion extendinginside the outer lip and beneath the inner lip, which holds the strip tothe body portion by the joining cement. By this method of manufacturethere is produced an extremely flexible all leather Welt insole having,however, a lip which is sufficiently strong to receive and hold theinseam stitches Without the necessity of reinforcement. As this novelinsole may be manufactured from thin or poor stock Without the necessityof subjecting the insole to a subsequent reinforcing or sole slashingoperation, a considerable economy in manufacture is effected, aswillreadily be understood by those skilled in the art.

The nature and scope of the present invention having been indicated andthe preferred embodiment of the invention having been specificallydescribed, What is claimed 1s:

1. A double-lipped all leather insole, comprising a sole shaped blank,having the inner lip of the insole formed on its marginal portion and aWedge-shaped strip secured beneath the inner lip to the periphery of theblank along its shank and forepart, said strip having its outer edgesplit substantially throughout its length and upturned against the innerlip, thereby forming the outer lip and feather.

.2. A double-lipped all leather insole, com-- prising a sole shapedblank, having an inner lip formed by upturning the entire "thickness ofthe marginal portion of the blank, and a Wedge-shaped strip arrangedparallel thereto consisting of an upturned portion forming an outer lip,a portion outside of said outer lip forming a feather, and portioninside of said outer lip and beneath the inner lip by which the strip issecured to the blank.
